Senior Backend Engineer (all genders)

Working with AI coding agents (a real part of this role)

We use AI coding agents (Claude Code) every day as a core part of how we build. We expect you to as well. Concretely, we're looking for someone who:

• has shipped production code with an AI coding agent,
• can describe their workflow - how they spec, prompt, review, and integrate agent output,
• has informed opinions on where agents fail and how they guard against it (review discipline, tests, architectural guardrails)

This isn't a buzzword for us - it's how the team works, and our hiring process reflects it (below).

Nice to have

• Event-driven/ CQRS /outbox experience
• Google Cloud Platform
• Migration or legacy-extraction experience(incrementally replacing an older system)
• Comfortable reading unfamiliar or legacy codebases

How we hire

• First Interview with People & Organisation (~25 minutes) - We want to get to know you better in a first meeting and you will get to know RECUP's culture, values and vision and understand yourself better for a mutual fit
• Meet Hiring Manager (Tech Leader) (~25 minutes) - Understand the RECUP platform from a technical perspective
• Our take-home case (~55 minutes) is AI-agent-assisted by design - use your preferred agent, as you would on the job. We don't test memorized syntax; we assess engineering judgment: how you specify work, catch and correct the agent, and make architectural decisions. Expect a brief take-home plus a live pairing and design session
• Meet the Team (Tech Lead and Engineer) + live AI coding session (extension of our take-home test) (~55 minutes) - Experience working with your new team.
• Meet our Co-CEO (~25 minutes) - Gain insight into our product and business

WAS WIR BIETEN

• The opportunity to make an impact at a company that combines economic growth with real, sustainable impact
• Flexible working models (flexible hours, remote work)
• Room for development and ownership: you actively shape your area
• A personal, professional culture and open feedback culture
• A dynamic, growth-oriented environment in a scale-up phase
• Partnerships with Wellpass, Urban Sports Club, Open Up and Future Bens

Want to help us write reusable packaging history?

Then we look forward to your application: send us a short, punchy cover letter and your CV via the application form. What matters to us are your skills, your experience and above all whether you identify with our values and company culture. Since we too are not entirely free from unconscious biases, we kindly ask you not to include a photo.

Where can we still improve?

We want to become more diverse because we believe that we can only achieve our vision through diversity, and that innovation can only emerge through diversity. We therefore welcome applications from people with international backgrounds, people of all gender identities, all age groups, people of color, and people with disabilities or chronic illness.
